# How does the cerebellum contribute to cognitive functions?

## TL;DR

This paper explores how the cerebellum, known for motor control, also contributes to cognitive functions like memory and language.

## Contribution

The paper identifies unresolved questions and roadblocks in understanding the cerebellum's role in cognition.

## Key findings

- The cerebellum's role in cognition is well-supported by anatomical and neuroimaging evidence.
- A unified theory explaining the cerebellum's cognitive contributions remains elusive due to unresolved key questions.

## Abstract

Over the past 70 years, neuroscience has gained a deep understanding of how the cerebellum supports basic motor functions. Anatomical, clinical, and neuroimaging studies, however, have also firmly established that the cerebellum holds an important role in cognition. Even though this topic has received considerable attention, we still do not know the exact nature of this contribution. This Unsolved Mystery reviews known facts about how the cerebellum contributes to cognition and identifies roadblocks that have prevented the development of a unified theory. Addressing these key questions should help the field develop the testable, falsifiable hypotheses that are needed to solve this intriguing question.

The role of the cerebellum in motor functions is well understood. But why is the same circuitry engaged in functions such as working memory, language, and social cognition? This Unsolved Mystery looks at the problems that have made it so difficult to answer this question and outlines strategies to make progress.
